HIGH-FREQUENCY MULTI-CRYSTAL OSCILLATOR Russian patent published in 2013 - IPC H03B5/36 H03B1/02 

FIELD: radio engineering, communication.

SUBSTANCE: high-frequency multi-crystal oscillator has an external housing with a main compartment and additional compartments, inner housings of micro-assemblies provided with compartments, main and auxiliary printed-circuit boards, thermostats, a thermistor, an electric heating element, low-pass power supply filters, buffer amplifiers, reference oscillation power adder, high-frequency self-excited crystal oscillators which are mounted in pairs on four printed-circuit boards, each connected to a separate low-pass power supply filter and a buffer amplifier.

EFFECT: design of a multi-crystal high-frequency temperature-controlled oscillator which enables to preserve the value of spectral power density of phase noise, as well as the level of technical noise and frequency stability of the output oscillation, typical of a high-frequency oscillator with one crystal resonator.
